Realtec
From Sega Retro
what do you think http://i.imgur.com/tdszG0d.jpg Realtec and Freetron mentioned on the same box. Now I've been tracking Freetron for a while - the made a bunch of slighty dodgy accessories in the early 1990s and also distributed a version of Sangokushi IV... somewhere. Same company? Similar company? Both would have been based in Taiwan -Black Squirrel (talk) 06:29, 20 March 2015 (CDT)
